The test jig includes movable probe, test support body and connecting wire, the movable probe includes the probe, sets up the middle part of probe with stop nut that probe fixing connects and with limit baffle and setting that probe relative motion connects are in spring between stop nut and the limit baffle, the test support body be the empty stomach siphonozooid on an empty stomach along radially setting up the penetrating probe pin hole who passes the central axis on the siphonozooid the external portion of test jig is right probe pin hole seals, the movable probe passes but installing of test support body up -and -down motion among the test support body. The utility model discloses can guarantee to measure accuracy and precision, alleviate the end of probe wearing and tearing simultaneously, prolong life. Installation, dismantlement and easy maintenance, it is more convenient to measure.
Description
Technical field
The utility model relates to graphite electrode detection technique field, particularly relates to a kind of testing jig of graphite electrode Instrument Measuring Resistivity of Carbon Products.
Background technology
In the graphitization process of manufacture of graphite electrode, for ensureing the stable of product quality, need to test shove charge and the resistivity of graphite electrode product of coming out of the stove, a medium scale graphite electrode factory needs the electrode blank tested to be about hundreds of thousands to prop up every year.The graphite electrode Instrument Measuring Resistivity of Carbon Products that currently available technology generally uses, is made up of testing jig, four probes and connection wire.Probe is fixed among testing jig, needs insulation processing between testing jig and probe.One end of probe contacts with tested graphite electrode, and the other end of probe is connected with wire, another termination tester of wire.This tester has easy to operate, that precision is higher feature.But this tester is under access times frequently situation, is connected because probe rigidly fixes with testing jig, probe is is easily worn and torn.Make it can not contact completely with electrode surface after probe wearing and tearing, both caused resistivity measurement precision to reduce, cause again testing jig shortening in serviceable life, and this testing jig uses inconvenience, wire is connected and maintenance difficult with probe.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of measuring accuracy is high, the testing jig of the graphite electrode Instrument Measuring Resistivity of Carbon Products of operating period limit for length and easy maintenance.
The technical solution adopted in the utility model is: a kind of graphite electrode Instrument Measuring Resistivity of Carbon Products testing jig, comprise movable probe, test support body and be connected wire, described movable probe comprises probe, the stop nut that the middle part being arranged on described probe and described probe are fixedly connected with and the postive stop baffle be connected with described probe relative motion and the spring be arranged between described stop nut and postive stop baffle, described test support body is insulation tube, described insulation tube is disposed radially the penetrating probe aperture through central axis, in described testing jig external body, described probe aperture is closed, described movable probe is arranged among described test support body through described test support body is moving up and down.
Further, described movable probe is 4, is evenly arranged on described test support body vertically; Described probe tails is helicitic texture, arranges two wire hold-down nuts in probe threaded exterior end; Described test support body insulation tube is round tube; Described probe aperture is circular, and the aperture of described probe aperture is greater than the diameter of described stop nut and postive stop baffle; On described test support body, handle framework is set.
The utility model employing beneficial effect is: owing to adopting movable probe and insulation tube test support body, after end of probe wearing and tearing, under the action of the spring, probe cephalad direction can do certain distance displacement, probe is kept in touch with tested graphite electrode, ensure that measurement accuracy and precision, alleviate end of probe wearing and tearing simultaneously, extend serviceable life.Between movable probe and test support body and installs between wire and probe, to dismantle and easy to maintenance, arranging handle framework is that measurement is more convenient.
Accompanying drawing explanation
Fig. 1 is the utility model testing jig schematic diagram;
Fig. 2 is the utility model testing jig movable probe cut-open view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of graphite electrode Instrument Measuring Resistivity of Carbon Products testing jig, comprise movable probe 11, test support body 2 and be connected wire 8, described movable probe is 4, is evenly arranged on vertically on described test support body.Arrange handle framework 12 on described test support body 2, the wire 8 of drawing from 4 movable probes 11 is connected to tester 13.
As shown in Figure 2, described movable probe 11 comprises probe 1, be arranged on stop nut 5 and the postive stop baffle 4 be connected with the relative motion of described probe 1 and the spring 3 be arranged between described stop nut and postive stop baffle that the middle part of described probe 1 and described probe 1 be fixedly connected with, described test support body 2 is round insulation pipe, insulation tube itself can play insulating effect, do not need to carry out insulation processing to probe and test support body again, and more convenient when round tube is closed.The insulation tube of described test support body 2 is disposed radially the penetrating probe aperture through central axis, in described testing jig external body, described probe aperture is closed, described movable probe 11 is arranged among described test support body 2 through described test support body 2 is moving up and down, like this, to a certain degree wear and tear even if end of probe has, under spring force, can ensure that probe is remained valid with tested graphite electrode to contact.Described probe aperture is circular, and the aperture of described probe aperture is greater than the diameter of described stop nut 5 and postive stop baffle 4, can install movable probe 11 easily like this.Test support body 2 adopts external diameter 40mm, the interior insulation tube through 30mm, length 1.6 meters, and distance on request bores the open-work of 4 diameter 16mm.Probe adopts the copper rod of diameter 12mm, long 150mm, the spiral shell button of one end car 80mm, and the other end is polished the point of long 15mm taper.Spring diameter 14mm, long 30mm's.Stop nut is the copper nut of internal diameter 12mm, the hole of drill diameter 12.3mm in the middle of spacing catch.Put two copper closing caps 6 of arc at each probe aperture position of test support body 2, clamp with the closing cap 6 of two round clasps 7 by both sides probe aperture simultaneously.Two wire hold-down nuts 9 are set in probe threaded exterior end, wire can be connected easily.
